IMPLEMENT FOR SETTING BUTTON-FASTENINGS.

SPECIFICATION forming part of Letters Patent No. 290,680, dated December25, 1883,

Application filed May 31, 1883. (X model.)

To all whom it may concern.-

Be it known that I, WILLIAM E. HAGAN, of the city of Troy, county ofRensselaer, and State of New York, have invented a new and usefulImprovement in Button-Fastening 11nplernents, of which the following isa specification.

My invention relates to that class of devices which are used to attachbuttons to shoes and other articles by means of staples, and whichimplements are made to have two jaws pivoted by means of a tongs-joint,and constructed with two handles as extensions from the jaws, andwhich when forced together also bring the jaws together and force thestaple previously linked into the button-eye through the leather ormaterial intermediately placed, so as to turn up and clinch thestaple-prongs on the under side of the leather or material.

My invention consists, as will be subsequently described in detail, inthe combination, with the jaws of a button-attaching in.

engage with each of the prongs after they have passed through theleather or material, and

thus force the staple-prongs up into the leather to clinch, the wholeoperation of forcing the staple-prongs through the leather and turningthem upwardly being accomplished by simply closing the handles.

My invention also consists in the sub-combination of the parts-wherethey perform spe eific function, as will be designated in the claims. I

In the accompanying drawings, forming a part of this specification,there are shown five figures illustrating my invention, and in all ofwhich the same designation of parts by letterreference is used.

Figure 1 shows in a side elevation a buttonfastening implementcontaining my invention, the jaws of which are illustrated as opened anda button and staple shown as inserted in the upper jaw. Fig. 2illustrates the same parts in a side elevation as are shown at Fig. 1,but with the jaws closed and the button attached to the leather ormaterial by means of the outwardly and upwardly turned prongs of thestaple. Fig. 3 shows a cross vertical section taken through theimplement, button, staple, and intermediate leather or material on theline at m of Fig. 2. Fig. 4 illustrates in a plan view the top of theupper jaw and the slotted spring, with a button inserted within theslotted, spring and upper jaw. Fig. 5 is a plan view of the top of theunder jaw.

The several parts of the implement. and those constituting my inventionare designated by letter-reference as follows:

The upper jaw is indicated by the letter J, and the lower jaw at J.

The handles are designated at H, and the tongs-pivot joint at which theyare operated is indicated at P.

The letter S indicates a leaf-spring, which is attached to the handle at71/, and at its front is constructed with the slotted and turned-up enda. The front end of..the upper jaw, J, is also slotted, and constructedwith a crossrecess on its under surface, so that when a button, B,having a staple, U, linked into its eye, is inserted into the coincidentslots in the end of the spring and jaw, with the top of the staple inthe cross-recess, as the jaws are forced together, the button and stapleare firmly held and forced down, the latter passing through theintermediately-placed leather, and the staple-prongs 0, coming incontact with the upper surface of the under jaw, are turned with thesame facility be applied to any other kind of button-fastening implementconstructed with two jaws and handles and an intermediately-arrangedtongs-pivot.

The leading feature of my invention, as an attachment tobutton-fasteningimplements, relates to the application of an angular orcurved lever, that is pivoted between its ends to the under jaw of thedevice, with that end of the lever nearest to the tongspivot constructedto engage with the upper jaw in its descent, and thus force the oppositeend of the lever upwardly to crowd the staple-prong points (after havingbeen spread out by engagement with the upper face of the under jaw) upinto the leather. This lever is indicated at L, and is shown as passingthrough the slot F, made in. the under jaw, as being pivoted at O to theunder jaw in an offset, (1, made thereon, with its inner upturned end,m, adapted to engage with the descending upper jaw at m, and thus forceupwardly the front endof the lever L, (indicated at W.)

The letter S designates a spring attached to the under jaw, against therecoil force of which the front end of the lever is raised. The outerend of the lever has formed in it a bearing or pivot-opening, O, for thepassage of the journal or pin 1), and to the outer ends of the latter,and at their lower ends, 0*, are 1 pivoted the pistons n a, which areconstrn eted to work in guideways n a formed in the end of the lowerjaw, and made with their upper ends grooved and inclined from theirinner edges upwardly and outwardly, as indicated at w 10. As this upwardmotion of the front end of the lever L thus produced is adapted-toupwardly force the staple-prong points into the leather by thebifurcated upward extension of the front end of this lever when so made,or by the attachment of any well-known means to the end of the lever forsuch purpose, I do notlimit my invention of the lever L, as constructedto operate in connection with the jaws of the implement, to its furthercombination with the pistons and their mode of operation as I show anddescribe them..

Upon the upper face of the under jaw there is formed a groove, A, whichis slightly higher at its center than at its sides, the purpose of whichis to guide the staple-prongs while being spread out into theeoincidently-fbrmed grooves produced in the ends of pistons as the jawsof the implement are forced together. The points of the staple-prongsthus moved turn up slightly in the grooves on the ends of pistons, and,as soon as this is done, the inner end, an, of the lever L is arrangedto en gage with the descending upper jaw, which raises the outer end, m,of the lever, and the pistons are forced upwardly to crowd theprong-points of the staples up into theleather.

\Vhile I do not limit my invention to the precise form of lever shownand described, yet I do make it a condition of any modification of itthat the lever shall be pivoted to the dispensed with and the leverdivided longitudinally at its front end in two parts, and each part bepivoted at each side of the under jaw, and the inner ends of the twoparts united between the jaws, and, where thus united, adapted to engagewith the under jaws when the j aws come together. As thus made, thebifurcated ends of the lever may be turned up to take the place ofpistons, or the latter may be pivoted to the bifurcated ends of thelever; or any well-known means may be attached to the lever ends toforce the stapleprong points up into the leather.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s-

1. The combination, with the upper and under jaws of a button-attachingimplement, of an angular or circular form of lever, that is pivoted tothe under jaw, substantially as shown, and constructed at its endnearest to the pivot to engage with the upper jaw as the jaws close toraise the outer end of said lever, as and for the purposes herein setforth.

2. In a button-attaching implement, and in combination with the pivotedjaws thereof, an angular or circular lever, which is pivoted to theunder jaw between the ends of said lever, and at the end nearest to thepivot is constructed to engage with the upper jaw as the jaws close, twopistons pivoted to the front end of said lever, and vertical guidewaysfor the said pistons, constructed in the under jaw of the implement, asand for the purposes set forth.

3. In abutton-attaching implement, and in combination with the upper andunder jaws thereof, the lever L, pivoted between its ends to the underjaw, with its inner end, an, constructed to engage with the upper jaw asthe jaws close, the pistons n n, pivoted to the front end of the saidlever, the piston-guides #11 formed in the under jaw, the inclinedgrooves 10 w, formed in the piston ends, and the groove A, produced inthe upper surface of the under jaw, as herein shown and described.

4. In a button attaching implement, the combination of the lever L,attached between its ends to the under jaw of the implement, with itsinner end constructed to engage with the upper jaw as thejaws close, andthe spring S attached to the under jaw, and constructed at its free endto engage with said lever, as shown and described.

Signed at Troy, New York, this 28th day of May, 1883, and in thepresence of the two witnesses whose names are attached.
